Four dolomite national reference materials has been developed. The whole process including sample composition design, machining, homogenizing examination and standard value analysis have been done according to the requirements of GB/T 15000 《Directives for the work of reference materials》 and YB/T 082 《 Specification for CRMs for metallurgical product analysis》.The calcium oxide contents of reference materials are from 31.49% to 35.73%, the magnesium oxide contents are from 15.28% to 21.06%,the silicon dioxide contents are from 0.098% to 4.21%. The principal components were in a wide range of content while most of the other components changed with the principal component in linear variation which means nearly all of the dolomite varieties has been covered. |
